HYDROCARBON-BURNER.

Specification of Letters Patent.

Application filed November 16, 1911. Serial No. 660,638.

i To all whom it may concern tank is hermetically sealed and provided Be it known that I, JORGEN M. HANSEN, a citizen of the United. States, residing at North Chicago, in the county of Lake and State of Illinois, have invented a new and useful I-IydrocarbomBurner, of which the following is a specification. j

This invention has reference to improvements in hydrocarbonburners and particularly to a burner which may be fed with fuel by means of compressed air or steam.

The object of the invention is to compact and simplify the burner and the container for fuel, whereby the structure may be made in the form of a compact portable unit.

The invention as particularly set out in the appended claims will be readily understood from the following detail description based upon and taken in connection with the accompanying illustrative drawings, wherein:

Figure 1 shows thepreferred embodiment of, the invention in central vertical section.

Fig. 2 is a similar section through the retort. Fig. 3 is a plan View of the retort with the cover plate removed. Fig.4 is a longitudinal vertical section through one form of the burner. Fig. 5 is a longitudinal section through the jet device. Fig. 6 is a side elevation partly in vertical section of the same device from adifferent: viewpoint. Fig. 7 shows in elevation one of the valvesof the jet device. Fig. 8 is an end view of the other valve of the jet device, showing the operating disk. Fig. 9 is a fragmentary view, showing a modified form of theretort.

The complete furnace illustrated as embodying the invention comprises a tank 1,

constituting a joint reservoir for the water 2, the oil 3 and air 4 the latter being introduced under pressure at 5-by means ofan air pump or other suitable pressure device. Asight gage 6 is arranged in the lower portion of the tank in order to indicate thedividing line between the water and oil. This with a pressure gage 7 by means of which the pressure therein/can be readily determined. I

7 Upon suitable standards 8 extending upwardly from the tank issupported a drum 9 open below and closed above by the domeshaped cover 10,havinga centrally arranged annular upstanding flange 11 to which is bolted or otherwise suitably secured the flue 12, which depends therefrom centrally with-- in the drum 9. This fine, which is open above and below, supports in itslower end a Patented Jan. 7, 1913.

retort 13, which comprises a thimble 14 divided by a transverse web. 15 and provided with diametrically arranged bosses 16. Each end of the thimble is threaded as at 17, for

engagement with the interior threads of top and bottom cover plates 18 and 19, these plates having marginal flanges 20 and 21, which overlie an annular flange 22, which surrounds the thimble midway of its length and of which the bosses 16 are-radial 6X:

tensions. Gaskets 23 and 24 are arranged between the marginalflanges'20-and 21 and the annular flange to effect a tight closure,

when the cover plates are screwed down by means of polygonal projections 25- and 26. Beneath the retort is disposed a burner 27, of any suitable shape though shown in the form of a bar or pipe, closed at each end, and'provided with apertures preferably in i the shape .of transverse slots 28, spaced'" apart along one face of the burner. About the central portion of ,the burner is arranged a fuel inlet 29, whiohmay be formed integral therewith or threaded into the same as illustrated. This fuel inlet hasde-- pending inwardly converging walls 30, pro-* vided with slots 31for the admission of ex.

traneous air, thus forming a mixing cham- ,ber. Upon theoppositeside of the burner co-axial with the fuelinlet is' a larger. gas

orifice 32, controlled by: the valvej83 carried by the stem 34. v,

The fuel inlet 29 of the burner is arranged to receive the upper end of a jet'device 35,

comprising a casing 36 provided with the,

central longitudinal bore 37 having an interiorly threaded portion '38and an enlargementor chamber 89,, and also interiorly threaded at 40. YTheforwaidend 0f the casing is reduced at 41 forminga shoulder 42 and exteriorly threaded at 43. to receive the interiorly threaded cap 44,havingga central opening 45 corresponding co-axially withthe boreof thecasing. The inner face of this cap is coned at 46 to receive the correspondingly exteriorly coned end 47 .of a

valve 48, said valve being exteriorly threaded at49 for engagement with the threads38 to provide for longitudinal adjustment of the valve within said casing. The valve 48 is provided with spaced grooves 48 extending longitudinally of the head 4-7 and connecting the annular space at 37 (Fig. 6) with the opening 45 when the valve is unseated. The casing 36 is also provided with a nipple 50 and with a radial bore 51 eX- tending therethrough into communication with the interior bore 37, said nipple being screw threaded to effect a coupling to the supply pipe, as will be hereafter described. The valve 48 is likewise provided with an axial bore 52, alining with the opening 45 of the cap. This bore is enlarged to form an interior chamber at 53, which is in communication through radial ports 54 with the chamber 39 formed by the enlargement in the bore of the casing previously referred to. This chamber is also provided with a radial channel 55, passing through the wall of the casing and the nipple 56 and also threaded similarly to the nipple 50 for the reception of a coupling.

The valve 57 is disposed within the chamber 53 to seat upon the bore 52 and control the same, said valve having its stem in threaded engagement with the first valve at 58 for longitudinal adjustment relative thereto. Packing glands 59 and 60 are disposed about the valve stems, one in thread ed engagement with the casing at 40 and the other threaded into the stem of the first valve at 61. The outer valve member 48 is provided with an operating wheel 62, formed as a crown pinion with teeth 63 in its face in mesh with the teeth 64 of a pinion 65, mounted upon the operating shaft 66 journaled between the two forks 67 and 68 of the bifurcated arm, 69, formed integral with the casing 36. The stem 70 of the inner valve is provided with a hand wheel 71 in which are formed peripheral sockets 7 2 for the reception of a pin 73', which projects between the forks 67 and 68 and is guided thereby for axial movement while angular movement of the same is prevented.

The water pipe 74 extends from the lower part of the reservoir upwardly and dis charges into the right hand side of the upper chamber 75 of the retort. This water pipe is provided with a manually operable valve 76 and a checkvalve 77.

An oil pipe 78 extends from the oil space of the reservoir upwardly and discharges at the bottom of the lower chamber 7 9 of the retort, this pipe being provided with a manually operable valve 80 and a check valve 81. A steam pipe 82 extends from the upper part of the chamber 75 downwardly to a point opposite the jet device to a T 83, and thence through the pipe 84 coupled to the nipple 56 into the chamber 39 of the jet device. An air pipe 85 provided with a manually operable valve 86 extends from the upper portion of the air space of the reservoir to the T 83, whence the air is also conducted by means of the pipe 84 to the chamber 39. The gas pipe 87 leads from the upper portion of the retort chamber 79 to a coupling with the nipple 50, and thence by the channel 51 to the interior chamber 37.

In some cases it may be found desirable to provide an upwardly opening check valve 88 in the air pipe 85 above the valve 86 and a downwardly opening check valve 89 in the steam pipe 82 above the T 83, although not ordinarily needful.

The operation of the device is as follows: The tank 1 of the reservoir having been supplied with water, oil and air under pressure, the valve 80 is opened permitting the oil to fill the retort and flow by means of the pipe 87 to the chamber 37. The valve 86 is then opened to admit compressed air to the chamber 39 and by operating the shaft 66 or by direct application of the hand to the disk 62, the valve 48 is retracted within the casing 36 so as to withdraw said valve from its seat 46 and permit the oil to flow from the chamber 37 through the nozzle 45. It will be noted from an inspection of Figs. 6 and 7 that the threaded connect-ions between the valve 48 and the casing 36 at 38 is by a right hand thread, while the engagement between the valve 57 and the exterior valve 48 at 58 is by a left hand thread. As the valve disk 62 and the valve 48 are rotated anti-clockwise to open the same, a relative contra-movement is imparted to the valve 57 by reason of its left hand thread and from the fact that it is held against actual rotation by the pin 73, thus the opening of the valve 48 operates simultaneously to open in a corresponding degree the valve 57, the ratio of such opening depending upon the relative pitch of the threads at 49 and 58. The relation between the two valves is also made adjustable by the position of the plurality of sockets 72 for the alternative reception of the pin 7 3. The oil is by the compressed air atomized at the nozzle 45 and injected through the fuel inlet 29 into the burner 27. At this time the burner valve 33 is removed from the opening 32, so that gas on being ignited burns at the opening 32 immediately beneath the retort. As soon as the retort becomes sufficiently heated water is admitted thereto through the pipe 74, which flashes into steam and is conducted by the pipe 82 to the chamber 39, where it takes the place of compressed air, which is then shut off by the closing of the valve 86, and the supply of oil to the chamber 37 is substituted by a supply of gas as the oil within the retort chamber 29 becomes vaporized. Thereupon the valve 33 is closed by its stem 34 and thereafter the gas injected into "said burner by the 'steam is burned in conjunction therewith at the slots 28, the combustionv being practically perfect and resulting in an intense heat available for use in the heatingofa room by means of the flue l-2and drum 9, or the device may be placed within a stove or the like and employed to heat articles above the same. 4

It will be understood that while the draW- ings illustrate a practical form of the invention, the latter is susceptible of various changes and modifications so long as such changes do not mark any material departure from the salient features of the invention.

In Fig. 9 is shown a modified form of retort, wherein the body 13 is dispensed with and the upper water chamber 75 is replaced by a water coil 7 5 fed by the water pipe 82 and in turn supplying the steam pipe 74. The oil vaporizing chamber 79 is also in this case substituted by the oil vaporizing pipe 7 9 which is fed by the oil pipe 78 and supplies in turn the gas pipe 87 The steam pipe 74* leads by way of the pipe 843 to the steam chamber of the jet device 35 and the gas pipe to the gas chamber as in the former case.
